Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.

THE BATTLE OF TALIKOTA and the destruction of Vijaynagar (Hampi)
26 January 1565

A tale of valor, deception and decimation.

A grim reminder that if we fail to protect our heritage, it will eventually crumble under the onslaught of "forces of anarchy".
(Elaborate thread)

This decisive battle was fought between the Vijayanagara empire and the Deccan sultanates resulting in a rout of Vijayanagara and ending the last major medieval era Hindu kingdom in south India.(1)

The seeds of 1565 encounter were sown more than 250 years earlier when the forces of the Delhi Sultanate, during the time of Alauddin Khilji and later Md Bin Tughlaq swept through southern India in an expansion spree.(2)

By middle of the 14th century, facing rebellions, Tughlaq withdrew to Delhi, leaving behind 2 empires, Bahmani, which ruled the Deccan from Kalaburagi, and Vijayanagara, which ruled most south India with its capital at Vijayanagar.(3)

The Raichur Doab, between the Krishna and Tungabhadra rivers, existed as a natural boundary between these two kingdoms, with wars often breaking out over control of this territory.(4)

This week, 33 years ago, Thomas Sankara, the revolutionary leader of Burkina Faso, was assassinated in a French-backed coup. He aspired to an egalitarian, feminist society, and an economy built on self-sufficiency, ecological regeneration, and independence from Western powers.

As debt crises mount across Africa, his ideas are more vital now than ever. I wrote about Sankara's legacy in these two pages from The Divide:

Today, Sankara's legacy is inspiring a new generation of revolutionary thinkers and activists across the continent and beyond. As Sankara himself put it, with uncanny prescience, “You can assassinate revolutionaries, but you cannot kill ideas”.

Sankara knew his assassination was coming. Speaking to African leaders at the OAU, he said "I would like this conference to clearly declare that we will not repay the debt; we must do it together, to avoid being assassinated individually..."

"...If Burkina Faso is the only one to refuse, I will not be here at the next conference."

In this thread, I will argue that the conventional wisdom that Shannon's information theory is all about syntax and not about semantics stems from superficial reading. On the contrary, even his 1948 BSTJ paper is already concerned with syntax, semantics, *and* pragmatics. 1/14

Of course, it does not help matters that Shannon himself states that "semantic aspects of communication are irrelevant to the engineering problem" of communication on the first page of his paper. But you have to read the entire paper, not just the first page. 2/14

Let's first pin down the notions of syntax, semantics, and pragmatics in the sense of Charles Morris: syntax is about relation of symbols to other symbols, semantics is about their relation to objects, and pragmatics is about their relation to subjects. 3/14

Let's start with pragmatics. The full formulation of Shannon's theory is concerned with the problem of reliable communication of some state of the world over a noisy medium, subject to a fidelity criterion. This is an operationalist, pragmatist concern. 4/14

We may envision the problem where we take an action U contingent on the state of the world X and incur the cost c(X,U). We cannot access the state of the world directly, but must mediate the act of selecting the action through transmission of symbols over a noisy channel. 5/14

How to not run/and run a business:

In 1976, my family was Big Thompson River flood. 2 hotels survived -locally owned one we were in, which let people stay free & doubled up rooms, & Holiday Inn, which tripled rates. I’ve never again stayed in HI for 45 years because of that..1
